- Powering over 500 Boeing 757 aircraft around the world
- There are over 1050 RB211-535 engines in service today
- 60 per cent of Boeing 757 operators have selected RB211-535 engines
- RB211-535 engines have logged over 61 million flight hours and over 22 million cycles of highly reliable service by January 2014
- In service with more than 60 operators
- The world's most reliable large turbofan
- High time on-wing engine has completed 40,531 hours without a shop visit
- Sole Western powerplant available on the Tupolev Tu-204 aircraft
The three-shaft architecture, first introduced on the RB211-22B, allows an engine to have fewer stages giving a shorter, stiffer structure. This technology allows the rotors to run to their optimum speeds thereby reducing the need for compressor variable guide vanes.
The hollow, titanium wide-chord fan blade, pioneered by Rolls-Royce and introduced into airline service in the 1980s, set new standards in aerodynamic efficiency and resistance to foreign object damage. Designed specifically for high-bypass turbofans, the width of these blades sets them apart from the narrow and less efficient earlier equivalents.
Best performance retention
The RB211-535E4 has the lowest combination of in-flight shutdown rate and shop visit rate in the airline industry, a factor that has resulted in the RB211-535E4 being the airlines first choice to power the Boeing 757. The RB211-535E4 achieved the world record for on-wing life without removal for over 40,000 hours over nine years in operation. This is equivalent to 18,000,000 miles flown, or 37 return trips to the moon. It stays on wing almost twice as long as any other engine on the airframe.
Through the Rolls-Royce concept of family designs, the RB211-535E4 was upgraded with Phase 5 combustor technology from the 04 HP (high pressure) module developed on the Trent engine family.
Best environmental credentials
The RB211-535E4-powered Boeing 757 is the quietest airliner in its class, meeting both Chapter 3 and Chapter 4 limits with a large margin, allowing it to power aircraft in and out of airports with strict local noise limits.
This coupled with Phase 5 combustion technology makes the RB211-535E4 the most environmentally friendly engine for the Boeing 757 and the Tupolev Tu-204.
The RB211-535E4 & RB211-535E4B variants have a common bill of material and are fully interchangeable. The Foreign Object Damage (FOD) resistant wide chord fan makes a strong, durable, and easily maintained engine that achieves the highest time to shop visit in its class. It has a large economic advantage on maintenance costs on a $/EFH basis and Rolls Royce offers a range of maintenance cost programmes that have helped to reduce the cost of ownership of RB211-535E4 engines. There are also smaller cost advantages such as lower brake wear, line maintenance, disruption and transportation.The RB211-535 is a three-shaft high-bypass-ratio engine.
